given,
f(x) =3x² - 4x - 6
then,
f(1) = 3(1)² -4(1) -6 = 3-4-6 = -1 -6 = -7
f(2) = 3(2)²-4(2) -6 = 12 - 8 -6 = 4-6 = -2
f(3) = 3(3)²-4(3)-6 = 27 -12 -6 = 15-6 = 9
f(x) =3x² - 4x - 6
then,
f(1) = 3(1)² -4(1) -6 = 3-4-6 = -1 -6 = -7
f(2) = 3(2)²-4(2) -6 = 12 - 8 -6 = 4-6 = -2
f(3) = 3(3)²-4(3)-6 = 27 -12 -6 = 15-6 = 9
